The report contains drainage-area values for: lakes and ponds included in the Maine Informational Display Analysis System (MIDAS) File 906-Z, streams that drain an area greater than 25 mi 2 , dams, and hydrologic data collection sites. Supplemental information in the report includes State and Federal location systems used to identify these lake and stream sites.

The area discussed in this report includes about 1200 square miles in southwestern Maine. Location of the area is shown on the cover, and a sketch map identifying the topographic quadrangles for the study area is given in figure 1. The northern boundary of the area is the divide between the Androscoggin River drainage basin on the north and the Saco, Presumpscot, and Royal River drainage basins on the south. The western boundary is the Maine-New Hampshire State line, and the southwestern boundary is the Little Ossipee River. The southeastern boundary is the mid-latitude of the Gray and Freeport 15-minute topographic quadrangles. The greatest part of the area is in Cumberland and Oxford Counties, a smaller area is in York County, and a small fraction is in Androscoggin County. Included are parts or all of 15 towns in Cumberland County, 15 towns in Oxford County, 5 towns in York County, and 2 towns in Androscoggin County. The report contains geologic and hydrologic data collected as part of an investigation of the surficial geology and ground-water resources made by the U.S. Geological Survey in cooperation with the Maine Public Utilities Commission. These data are made available for use in planning the development of natural resources. An interpretive report containing maps of surficial geology and ground-water availability and related geologic and hydrologic information will be published in the Survey's Water-Resources Investigations series.
Water resources data for the 1978 water year for Maine consist of records of stage, discharge, and water quality of streams; stage and contents of lakes and reservoirs; and water-levels and water quality of wells. This report contains discharge records for 68 gaging stations; stage only for 2 gaging stations; contents for 17 lakes and reservoirs; water quality for 13 gaging stations and 22 wells; and water levels for 22 observation wells. Additional water data were collected at various sites, not part of the systematic data collection program, and are published as miscellaneous measurements. These data represent that part of the National Water Data System operated by the U.S. Geological Survey and cooperating State and Federal agencies.
An oil spill near a breeding colony could result in the transfer of oil from the plumage and feet of incubating birds to their eggs. Microlitre amounts of No. 2 fuel oil were applied externally to common eider eggs in an island breeding colony in Maine. Clutches of eggs treated with 20 ?l of fuel oil had significantly greater embryonic mortality than the control clutches when they were examined 7 days after treatment. The results are similar to those of an earlier study of artificially incubated common eider eggs and indicate that nest site conditions do not affect embryotoxicity of No. 2 fuel oil.

Physical properties, including density and strength, of the Lucerne Granite (Wing, 1958) vary because of inhomogeneities caused by fracturing and differences in texture. Two granitic facies were found: a coarse-grained variety in the southern part of the body and near the edges of the pluton and a medium-grained porphyritic variety in the central and northern sections. Point-load strength tests indicate that the medium-grained porphyritic granite is stronger than the coarse-grained porphyritic or non-porphyritic granite. Results of bulk and grain density tests suggest that rock strength in the weaker granite samples is controlled by microfractures. In the pluton, joint trends changed from a scattered pattern in the north to a preferred orientation in the south. Because it has a simple joint pattern and is homogeneous in texture, the southern part of the Lucerne Granite is a more suitable area for excavation and fluid storage than the northern section.
Outbreaks of avian cholera ( Pasteurella multocida ) occur frequently in common eiders ( Somateria mollissima dresseri ) in Maine during early summer. Studies over a seven year period show that over 90% of the loss occurred in incubating females and might be associated with their weakened condition because females and might be associated with their weakened condition because females do not feed during the incubation period. High nesting densities also may contribute to the losses. The exact source of P. Multocida is unknown although carrier birds were found.

The earthquake data for the state of Maine shown on this map and listed in table 1 was taken from the U.S. Geological Survey catalog of earthquakes (Hays, and others, 1975). This list of earthquakes was originally compiled for use in preparing the Seismic Risk Studies in the United States (Algermissen, 1969) and has been updated through 1974. The catalog is reasonably complete through 1974; possible discrepancies with existing publications may exist, however, because the file was compiled over a long period of time and by a number of compilers.
A major business section of Bangor, Maine's third largest city, was flooded with depths of water up to 12 feet on February 2, 1976. The flood elevation was 17.46 feet above National Geodetic Vertical Datum (NGVD) of 1929 at the Washington Street bridge over Kenduskeag Stream and was the third highest known flood elevation since 1846. The flood, which was due to an ocean surge coming up the Penobscot River, is the first documented major flood of this type in Bangor. This report contains flood elevations in the city of Bangor and along the coast of Maine, east of the Kennebec River. Also included are data on meteorological, hydrological, and marine conditions associated with the intense winter storm.
Water resources data for the 1975 water year for Maine consist of records of stage, discharge, and water quality of streams; stage and contents of lakes and reservoirs; and water-levels and water quality of wells. This report contains discharge records for 65 gaging stations; stage only records for 1 gaging station; contents for 17 lakes and reservoirs; water quality for 33 gaging stations and 11 wells; and water levels for 12 observation wells. Additional water data were collected at various sites, not part of the systematic data collection program, and are published as miscellaneous measurements. These data represent that part of the National Water Data System operated by the U. S. Geological Survey and cooperating State and Federal agencies.
